Another long shot. Are there any irregularities in the shape of the body or leads of the parts that are skewed? Any flash from the molding process for example? Almost all SOT-23s that I have seen are basically perfect but I seem to remember seeing so

Are you having problems with alignment of BGA's or perceiving that you will have problems. We run thousands and they re-align very well with leadfree if slightly off - Do you handplace all your BGA's? I would imagine there would be cosiderable cos

I believe the Led's should flash 3 times when the card is booting up/ powering up normally. There was no board troubleshooting back in the day and we just replaced the card. Make sure the metal cover is grounded to the machine.....this sometimes caus

IF and only IF you are on a solid flooring. We have ESD carpet. If you were to apply RTV to the carpet, you'd be walked out and thrown on your skinny a$$. Also, extruded aluminium conveyors will bow before skidding, thus causing alignment problems

So what your telling me is kind of vague. Does the machine home and go to the front left corner of the machine? If it does....this could be a quad align problem....meaning dirt on the lens or so-forth. You should watch the heads homing in the z-axi

There is problem with the alignment of BGA Balls. Check for any vibration. http://hubpages.com/hub/SMT-Reflow-Soldering-Equipment

I would change the Quad Align cable. If you have a spare head board swap that out as well. Make sure your Quad Align lenses are clean. If the camera is smudged then you can have some problems aligning parts as well. Let us know what you find. Cheers.

I dont think you are going to find schematics for that board. Looking through my old stuff....i dont have it and i dont recall it being in the schematics. Maybe someone else can get you a set of schematics though. Good Luck
